This material was some of the first to come out of Bolivia in a long time. This piece features dozens of large (for this mine), sharp, highly lustrous, gemmy crystals measuring up to 8.5 mm of Augelite associated with greenish-brown compressed rhombohedra of Siderite with Pyrite and micro Quartz on matrix. This specimen is from the find about 7 years ago, when some of the most impressive Augelites came out of Tazna.
